The cause seems to be a change in the master pom:
the maven-compiler-plugin plugin now has the below section which was not
there in 2.7.
If I take it out and build only log4j-perf, the benchmarks run without
error. (But building all modules fails: some problem in log4j-core...)
<executions>
<execution>
<!-- disable annotation processing for first pass -->
<id>default-compile</id>
<goals>
<goal>compile</goal>
</goals>
<phase>compile</phase>
<configuration>
<proc>none</proc>
</configuration>
</execution>
<execution>
<!-- then do a processing-only pass to generate plugins .dat file -->
<id>process-plugins</id>
<goals>
<goal>compile</goal>
</goals>
<phase>process-classes</phase>
<configuration>
<proc>only</proc>
</configuration>
</execution>
</executions>
